1. An apparatus to measure differential pressure, the apparatus comprising:
a first housing including a first port, the first port fluidly coupled to a first location, first fluid to flow into the first port from the first location;
a second housing coupled to the first housing, the second housing including a second port, the second port fluidly coupled to a second location, second fluid to flow into the second port from the second location;
a piston slidably disposed between the first and second housings, the first and second fluids to cause movement of the piston, the movement of the piston corresponding to a differential pressure between the first and second locations; and
a pneumatic valve operatively coupled to the first housing, the pneumatic valve to move to an open position when the differential pressure is at or above a pressure threshold.
